Enable IBM FlashSystem FC driver

Kilo - Kilo - Kilo - Kilo - Kilo - Kilo - Kilo - Kilo -

Set the volume driver to the FlashSystem driver by setting the volume_driver option in configuration file cinder.conf as follows:

volume_driver = cinder.volume.drivers.ibm.flashsystem.FlashSystemDriver

To enable IBM FlashSystem FC driver, configure the following options in configuration file cinder.conf:

Table 2.16. List of configuration flags for IBM FlashSystem FC driver
Flag name	Type	Default	Description
`san_ip`	Required		Management IP or host name
`san_ssh_port`	Optional	22	Management port
`san_login`	Required		Management login user name
`san_password`	Required		Management login password
`flashsystem_connection_protocol`	Optional	FC	Connection protocol should be FC
`flashsystem_multipath_enabled`	Optional	False	Enable multipath for FC connections
`flashsystem_multihost_enabled`	Optional	True	Enable mapping vdisks to multiple hosts ^[a]
^[a]This option allows the driver to map a vdisk to more than one host at a time. This scenario occurs during migration of a virtual machine with an attached volume; the volume is simultaneously mapped to both the source and destination compute hosts. If your deployment does not require attaching vdisks to multiple hosts, setting this flag to `False` will provide added safety.
